BOXING on CASING menmn Application filed July 7,

This invention relates to improvements in machines for boxing and easing cans and more particularly to power-driven mechanism for operating such machines,-on e ohject of the invention being to provide simple and efficient mechanism operated by a motor for actuating the pusher member of a can boxing machine and to provide simple and efficient means whereby the operation of said mechanism may be readily controlled by an attendant.

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drmvings: Figure 1 is a view in side elevationshowlng an application of my improvements to a can boxing machine; s

Figure 2 is a plan view of a portion of the machine and a Figures 3 and 4 are views showing details. My improvements are shown in the drawing as applied to a boxing machine of the general type disclosed in patent granted to me on the 2nd day of September 1924 and designated by No. 1,507,387. The machine comprises a framework 1; an assembling frame 2 for cans and to which the cans are fed by suitable means so that they will be disposed in layers; a pusher 3 to enter the assembling frame and engage cans therein to move the layers of cans forwardly, and a lever frame 4 pivotally connected with the framework and connected with the pusher for operating the same. The lever frame 1 may be provided with arms 5 depending from the same at its pivotal mounting. Springs 6 may be attached at one end to theframework and thelr other ends to said depending arms so that they will operate to retain the pusher normally in and return the same to its retracted or withdrawn position.

Mounted in suit-able bearings 7, 7 on the fmmework, preferably over the assembling frame 2 is a shaft 8, and pivotally mounted between upper portions of the uprights of the lever frame 1, is a bar 9. The body of this bar may be angular and it is provided in its center with a transverse hole for the free passage of a rod 10, with one end of which. one end of a flexibledevice 11 is connected, the other end of the device 11 being #51 connected with the shaft 8. The rod 10 is threaded to receive a nut 12, between which 1927. Serial No. 204,115.

and the bar 9, a spring 13 is located so that the device shall have a yielding connection with said bar 9. In the embodiment of the invention shown in the drawing, the flexible device 11 is a strap or belt and it is connected with the shaft 8 preferably by means of a. hinge structure 14. I do not, however, re strict myself to the use of a belt or strap, as the flexible device 11 may consist of a chain or cable to wind on the shaft 8. It is apparent that if the shaft 8 be rotated in one directiointhe flexible device will be wound thereon and the pusher will be pulled forwardly and made to enter the assembling 70 frame and move the cams forwardly so as to be deposited into a box or case. The forward movement of the pusher will be against the resistance of the springs 6 so that when drivlng poweris removed from the shaft 8, said sprlngs will serve to cause the pusher to be retracted. The shaft 8 is driven by a motor 15 (preferably an electric motor) which may be convenientlymounted upon the framework in proximity to the assembling frame. The shaft 8 is extended at one end beyond one of its bearings and has secured thereto, a clutch disk 16 and with the latter, a clutch disk 17 loose on said shaft iscooperable. The loose clutch disk 17 is carried by a loose sleeve 18 $5 and these parts carry a sprocket Wheel 19. The clutch disk 17, sleeve 18 and sprocket wheel 19 may, if desired, be made in one integral structureloosely mounted on the shaft 8. A sprocket chain 20, transmits power from asuitable wheel on the shaft of the motor to the sprocket wheel 19 for imparting power to the shaft 8 when the clutch disks are in operative engagement with each other.

Arms 21, 22 project laterally from the framework and provide bearings for a shaft 23 having an arm 24 and this arm may be provided with aball-member 26 to engage the closed end of the sleeve 18. A. spring27 coiled on the shaft 23 and connected therewith and with the arm 22 tends to turn said shaft in a direction to relieve the pressure of y the arm 24 against the closed end of the sleeve 18. An arm 28 is secured to the shaft 23 and i is connected, through the medium of anadjustable connection 29, with a foot lever 30 suitably mounted in the lower portion of y the framework. It is evident that by pressing the foot lever, the arm 28 will be de pressed in a manner to turn the sh aft 23 and cause pressure of the arm 24 against the sleeve 18 to shift therclutch disk 17 into 7 pusher to release the clutch devices, said member being free of the pusher and the operator-controlled connections and actuated by impact from the pusher.

6, The combination in a boxing machine including a pusher and a lever connected therewith, of a motor, connections between the motor and said lever, said connections including clutch devices, operating means for the clutch devices, said operating devices ineluding an arm, and a spring-retained sliding wedge for moving said arm to release the clutch devices, said wedge having a part in the path of forward movement of said lever.

7. The combination in a boxing machine including a pusher and a lever connected therewith, of a motor, connections between the motor and said lever, said connections including clutch devices, operating means for the clutch devices, said operating devices in- :luding an arm, a set screw carried by said arm, a slide having a wedge end cooperable with said set screw, a spring for retaining said slide in and returning it to normal position, and an adjustable screw carried by said slide and disposed in the path of forward movement of said lever.

In testimony whereof, I have signed this specification.
